Well, applied tested it on both rhel7, fedora21 and rhel6.6, seems to work,
have it in my perf/core branch at, that branch now builds on
rhel6.6, after fixing issues with several patches that were making it shadow

If we can get a better message for that, figuring out what that
_IS_TRIVIAL thingy does....
